A man whose son was murdered by the IRA in 1993 has called on Freddie Scappaticci to be investigated for his alleged involvement in the killing.

Frank Mulhern's solicitor Kevin Winters, who is representing a number of victims' families in civil cases against the alleged Army agent, the Ministry of Defence and the Chief Constable, is urging more people to come forward.

Joe Mulhern was just 22 years old when he was abducted by the IRA.

He was accused of passing information to Special Branch, interrogated for 10 days, shot and his body dumped near Castlederg, Co Tyrone.

No one has ever been charged or convicted of the murder.

Six weeks after he was buried his father Frank – who first spoke to UTV’s Insight programme in 2013 – said Freddie Scappaticci, who at the time was alleged to be a senior member of the IRA's internal security unit, told him about his son's murder.

Frank Mulhern said: “I asked him again how he died and Scap said that the first shot had hit my son in the back of the neck and he told the guy whoever shot him to shoot him again, so the second shot hit him on the back of the head and apparently that’s what killed him.”

Scappaticci was named in 2003 as the highest ranking Army agent working inside the IRA, a claim he consistently denies.

Frank Mulhern is convinced the security forces could have saved his son but chose to protect their spy codenamed ‘Stakeknife’.

“It’s about time Scap was brought to court and that’s all I really want,” he said.

Frank Mulhern, together with a number of other families, are now taking a civil action against Freddie Scappaticci, the Ministry of Defence and the Chief Constable.

Their solicitor Kevin Winters believes all the abductions and killings allegedly linked to Scappaticci, along with the role of the state in protecting the agent from prosecution, need to be fully investigated.

Frank Mulhern continued: “The PSNI have files which could solve a lot of these murders but for one reason or another they’re not acting on them, probably because Freddie Scappaticci is involved.

“I say my prayers at night and one of the prayers includes Scap, that he is brought to court and charged or whatever. I mean all I want is my day in court with Freddie Scappaticci – I want absolutely nothing else.”

Two divine persons in one. A mother lamenting her children in bondage. A girl ravished by the Saxon, who weeps over her stringless harp. But her young champions keep watch in the mountains, awaiting the dawn of the bright sun of Freedom. They will gather around her with pikes and swords.
